〔産業上の利用分野〕
本発明は炭素珪素焼結体同志を接合させるガラス組成の
接合材に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bonding material having a glass composition for bonding carbon-silicon sintered bodies together.
炭化珪素焼結体は高温構造材として期待されている。そ
れは熱伝導率か大きく、耐熱強度か高く、同時に耐摩耗
性、耐食性かあるからである。Silicon carbide sintered bodies are expected to be used as high-temperature structural materials. This is because it has high thermal conductivity, high heat resistance strength, and at the same time wear resistance and corrosion resistance.
しかし用途としてガスターヒンの内燃機関やロータ、高
精泥機械部品のように形状、寸法、精度なとの要求か高
い複雑形状な構造物の場合は予しめ一体形状て製作する
ことか難しい。このため単純形状の部品を作っておいて
、それらを接着して複雑な形状の構造体に仕上げること
か考えられる。However, in the case of complex-shaped structures that require high requirements for shape, size, and precision, such as internal combustion engines, rotors, and high-refined mud machine parts, it is difficult to manufacture them in one piece in advance. For this reason, one idea would be to make parts with simple shapes and then glue them together to create a structure with a complex shape.
この意味において接合技術か重要視されるようになって
きた。In this sense, bonding technology has come to be viewed as important.
この炭化珪素焼結体同志を接合する方法には珪酸アルカ
リ系、リン酸塩系、シリカツル系等の無機接着剤かある
か、この方法は接合温度か100〜400°Cと低く気
密性も悪く、強度、耐熱性も十分てない欠点かあった。Is there a method for joining these sintered silicon carbide bodies together using an inorganic adhesive such as an alkali silicate adhesive, a phosphate adhesive, or a silica vine adhesive? However, it also had the disadvantage of not having sufficient strength and heat resistance.
本発明の目的は炭化珪素焼結体同志を接合するために、
接合界面に気泡や熱膨張係数の差異などによる亀裂の生
しない接合強度か大である接合材を提供することにある
。The purpose of the present invention is to join silicon carbide sintered bodies together,
The object of the present invention is to provide a bonding material that has high bonding strength and does not cause cracks due to bubbles or differences in thermal expansion coefficients at the bonding interface.
(問題点を解決するための手段)
本件の発明者は、上記の問題点を解決するために比較的
低い共融点を持ち炭化珪素焼結体接合面に気泡、亀裂か
生しない酸化物ツルターガラスについて鋭意研究を行っ
た結果、上記の目的に適う接合用ガラス組成物を見出し
、本件発明を完成させるに至った。(Means for Solving the Problems) In order to solve the above problems, the inventor of the present invention has developed an oxide sulter glass that has a relatively low eutectic point and does not generate bubbles or cracks on the bonded surface of silicon carbide sintered bodies. As a result of extensive research, we have discovered a bonding glass composition that meets the above objectives, and have completed the present invention.
すなわち本件発明の要旨は、炭化珪素焼結体同志を接合
させるガラス組成てあって5i0240〜60重量%、
8020〜30重量%、Al2039〜20重量%、C
a0 3〜15重量%、Zr020〜3重量%よりなる
ことを特徴とする炭化珪素焼結体の接合ガラス組成物に
ある。That is, the gist of the present invention is that the glass composition for bonding the silicon carbide sintered bodies together contains 5i0240 to 60% by weight,
8020-30% by weight, Al2039-20% by weight, C
A bonded glass composition of a silicon carbide sintered body characterized by comprising 3 to 15% by weight of a0 and 20 to 3% by weight of Zr0.
前記の組成の限定理由を説明するとSiO□の含有量は
ガラスの熱膨張係数を炭化珪素の熱膨張係数に近い値と
するためには40重量%以上とすることか必要てあり、
又ガラス溶解温度を1450°C以下とするためには6
0重量%以下とすることか必要である。CaOはガラス
溶解時の融液の粘度を低下させ均質なガラスを製造する
ために不可欠てあり 3重量%未満ては粘度の低下か不
十分てあり、15重量%を越える場合には熱膨張係数か
炭化珪素焼結体のそれより大きくなる。Al2O3の量
は9重量%未満ては耐湿性か劣り、20重量%を越える
場合は溶融温度か高くなる。B2O3の含有量は20重
量%未満ては溶融温度か高くなり、30重量%を越える
場合はガラスの化学的安定性か低下し好ましくない。To explain the reason for the above composition limitation, the content of SiO□ needs to be 40% by weight or more in order to make the thermal expansion coefficient of glass close to that of silicon carbide.
Also, in order to keep the glass melting temperature below 1450°C, 6
It is necessary that the content be 0% by weight or less. CaO is essential for reducing the viscosity of the melt during glass melting and producing homogeneous glass.If it is less than 3% by weight, the viscosity will be insufficiently reduced, and if it exceeds 15% by weight, the coefficient of thermal expansion will decrease. or larger than that of silicon carbide sintered body. If the amount of Al2O3 is less than 9% by weight, the moisture resistance will be poor, and if it exceeds 20% by weight, the melting temperature will be high. If the content of B2O3 is less than 20% by weight, the melting temperature will increase, and if it exceeds 30% by weight, the chemical stability of the glass will decrease, which is not preferable.
Z r 02は必須成分てはないか3重量%以下を含有
させることにより化学的耐久性を白玉させる効果かある
。Although Zr 02 is not an essential component, it is effective to improve chemical durability by containing it in an amount of 3% by weight or less.

残留を防ぐことかできる。Silicon carbide and oxide sulter glass are usually heated at 1000°C.
The above reaction causes foaming, and bubbles are present at the joint surface. Therefore, during bonding, it is desirable to perform the bonding under reduced pressure and at a rate of temperature rise and fall of 5° C./min or more, thereby preventing air bubbles from remaining in the bonded portion.

Further, the glass is ground into fine powder using an alumina ball mill or the like. The particle size of the glass powder used for bonding is preferably fine, for example, about 0.5 to 1 g'm.
